Overview
- The Presidency signed a joint resolution that formally added Cártel de Sinaloa, La Nueva Familia Michoacana, Los Tiguerones, FARC-EP and ELN to the Registro Público de Personas y Entidades vinculadas a Actos de Terrorismo y su Financiamiento (RePET).
- The measure was published in the Boletín Oficial as Resolución Conjunta 5/2026 and was coordinated by the Foreign Ministry, Security Ministry, Justice Ministry and the State Intelligence Secretariat.
- The official statement described the Colombian groups as Marxist-Leninist insurgents responsible for major humanitarian harm and described the Mexican and Ecuadorian groups as transnational criminal networks tied to drug trafficking and violence.
- The announcement did not list new domestic operations or ongoing Argentine investigations, leaving open whether the change will trigger immediate arrests, prosecutions or enforcement actions at home.
- The step follows recent U.S. counter-narcotics cooperation in Argentina, including a new INL regional unit and approved funding, and could ease information sharing, sanctions or asset-tracing with international partners through legal and administrative channels.
